An ephemeral lake is a temporary body of water that forms in arid or semi-arid regions, usually after heavy rainfall. These lakes exist for a short period before evaporating or draining away. Ephemeral lakes are significant in studying desert hydrology, sedimentation patterns, and the response of ecosystems to fluctuating water availability.
